Ambitious plans to roll out gigabit-speed broadband to every home in Britain by 2025 have been rolled back in Chancellor Rishi Sunak's spending review.

Now the aim is to have a "minimum of 85% coverage" by that date.

It will come as no surprise to industry watchers, who felt the target was unachievable.

The budget for the plan remains the same - £5bn, although the figure for next year's spend is much lower.

Now only £1.2bn of that £5bn will be made available up until 2024.

The National Infrastructure Strategy document said it will "seek to accelerate roll-out further to get as close to 100% as possible".

It is expected that commercial deployments of gigabit-capable fibre networks will reach more than 70% of premises by the end of 2025 anyway, without government intervention.

Exactly how green and how profitable are the electric bikes and scooters that millions of us are now renting?

Those were two of the big questions hanging over the industry as 2020 began.

Despite the huge disruption the pandemic brought, the biggest player in the market, Lime, now says it is profitable for the first time.

"There are some markets where we're hitting all-time high ridership," Lime chief executive Wayne Ting says.

Those include Seoul, London and Salt Lake City. For example, in London each vehicle is now being used an average of 4.5 times a day instead of about twice a day.

But there has also been some aggressive cost-cutting. As a privately-owned company, Lime won't disclose detailed numbers.

The year began with 14% of the workforce being cut - that's 100 jobs - and a retreat from 12 cities as the company ran short on cash.

Michael Cervenka traces his interest in engineering back to his grandfather's influence.

"He was an organ builder and had me sorting out screws on his workshop floor when I was 18 months old," he says.

That interest literally took off. He is now the boss of Bristol-based Vertical Aerospace, and has progressed to electric vertical take-off and landing (eVTOL) machines.

With the potential to be quiet and economical, these aircraft have been touted as the next big thing in passenger aircraft.

Vertical is working on the VA-1X, an aircraft intended to fly between regions. That regional emphasis matters as eVTOL machines have often been promoted as air taxis, whizzing around our cities under the banner of "urban air mobility" (UAM).
